Supply Portfolio


Clean Supply for Our Customers

Powerex provides clean, reliable and flexible wholesale electricity products to our customers across the Western electricity grid. Our contracted supply portfolio includes the residual system capabilities of the BC Hydro system, the Canadian Entitlement supply provided under the Columbia River Treaty, and numerous contracts for clean and renewable power resources throughout the Western electricity grid.

Powerex has adopted a voluntary Clean Energy Trade Standard - a standard that provides confidence to clean energy purchasers that their purchases represent truly surplus clean supply. The Clean Energy Trade Standard helps distinguish clean hydro systems as a fully credible and reliable source of clean supply that is not backfilled with fossil-fueled generation.

The Clean Energy Trade Standard positions Powerex to meet the rapidly growing demand for clean electricity from a range of customers, including corporate users that increasingly seek to demonstrate to their shareholders 100% clean electricity procurement as part of their corporate commitments, and load-serving entities in the West under a clean procurement requirement.


BC Hydro System Capability

Powerex has contractual access to the flexibility of BC Hydro’s world-class integrated system of over 17,000 MW of generating capacity – the vast majority of it from hydroelectric and wind resources owned or contracted for by BC Hydro. This system is interconnected with the Western U.S. by two 500-kilovolt transmission lines on the West Coast between B.C. and Washington State; one 230-kilovolt line connecting B.C. and Washington on the east side; and a 500-kilovolt line to the east, connecting B.C. with Alberta.
